Application filed April 4,

' To all whom it may concern:

Be it known that I, EARL W. Lnsnnn, a citizen of the United States,residing at Cleveland, in the countyot Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in and Relating toShingles, of which the following is. a specification. y

This invention relates to a roof, more par ticularly to the shinglestherefor. I One object of the invention is to-provide a plurality ofshingles forfroofingpurposes having along adjoining edges interlockingdevices, whereby they may be rapidly laid in spaced and alignedrelationship.

Another object of the invention is to pro vide a shingle which is so cutalong its opposite sides that it may be spaced from and align withanother'shingle or shingles of like construction to form adurable roofcovering.

A further object of the invention is to provide a shingle havingalongits opposite side edges complementary walls permitting theshinglesto be cut from a strip of material without waste and correlatedeconomically in spaced and aligned arrangement.

Anotherobject of the invention is to provide shingles for coveringpurposes each having along their opposite sides elements shaped forcorrelation with the elements on adjacent shingles to permit alignmentone with another and with the shingles comprising an adjacent row ofshingles.

A further object of the invention is to simplify the construction ofshingle disclosed in my co-pending application Serial No. @8546.

Other objects of the invention will be apparent to those skilled intheart to which my invention relates from the accompanying drawingstaken in connection with the following description.

In the drawings, Figure 1 is a perspective view of a shingle embodyingmyinven tion and made according to my improved process.

Fig. 2 is a plan view of a plurality of shingles showing them arrangedside by side.

and in sp'acedand aligned relationship.

Fig. 3 shows a plurality of rows of shingles illustrating themanner inwhich they are assembled and laid on a roof.

of matter, partly broken away, showing a portion extended and a set ofshingles ein- In the drawings, 1 indicates as an entirety a shingleembodying or constructed accord ing to my invention. To illustrate theapplication of my invention, I have shown in the drawings a plurality ofshingles arranged side by side and overlapping the shingles in anadjacent lower row, in the usual way, (see Fig. 3) to form a roof orroot covering. Each shingle maybe stamped out of suitable material, suchas asphalt or composition, by asuitable die, but in carrying out myimproved process, for economical reasons, I prefer to use knives orcutters, suitably mounted on a roller or rollers, and to cut theshingles from an endless strip or roll A of asphalt, as will be.understood from Fig. 4. When made in this last re erred to manner, I amenabled to avoid all wasteof material (except small portions a of thestrip along. the outer edges of the outer shingles of each set andsections a only one section being shownat the opposite ends 01 thestrip) and at the same time to so cut the strip of material that theinterlocking or interengaging devices on one edge of each shingle may becorrelated with the interlocking or inter-engaging devices on theopposite edge of the adjacent shingle to insure (1) proper spacing andalignment of the shingles in each row relative to each other and (2)overlapping of each row of shingles on the adjacent lower row ofshingles to effect uniform exposed surfaces of the rows in the completedroot covering.

To prepare the stripA for use in carrying out my process, I first cutthe free edge of the strip A along a broken line B to form threeoil'se'ts Z) each spaced from the adjacent side. edge of the strip orthe adjacent offset of the nextfshin'gle a distance equal to the widthof a. shingle, allowance being made for the projecting members i l onlongitudinal broken lines C, the outer ends of which coincides with theside wall of each offset Z), and which extend inwardly equal distancesfrom the inner ends of the offsets. In carrying out this step of myprocess I prefer to provide knives or cutters to make the cuts G and Owhich serve to provide the extensions and coinple1nen tary recesses, tobe later referred to, on the outer side edges of the end shingles ofeach set. In providing these cutters, I utiliaethe longitudinal edges ofthe strip A to form portions of the side edges of the outermostshingles, thereby using the full width of the strip and avoidingunnecessary waste of ma terial. I then cut the strip on thc trans versebroken lines D, D, to complete the cutting out of the set of shingles,and sever them from the body of the strip A. As shown, this latter cutserves to form the ends of the next set of shingles. It willhcunderstood, however, that these steps or operations may be reversed oreffected simultaneously. As shown, I am enabled to provide four shinglesfrom a single width of material. These operations are continued untilthe strip A is entirely out into shingles.

Each longitudinal cut is formed with a plurality of offsets 2, 8, toform on one side edge of one shingle a pair of extensions 4i, 5, (thelatter being twice the length of the former) and on the adjacent sideedge of the adjoining shingle complementary recesses 6, 7. Theextensions at, 5, are preferably connected or merged together, as shownin the drawings to facilitate the cutting thereof. As shown, the offset3 is spaced from the transverse cut D and the offset 2 is spaced fromthe offset 3 a distance e ual to the length of the offset Z), respective y, so that each of the extensions 4-, 5, and each of thecomplementary recesses 6, 7, is of the same width and of a width equalto that of the offsets b. In laying the shingles 1 side by side in rows,the extensions 5 of one shingle fits into the recess 6 of the adjoiningshingle with its lower end wall 3" formed by the offset 3 ininter-engagement with the end wall 2 of the recess formed by he offset2. As the extension 5 and recess 6 are of a width equal to the length ofthe offset 5, it will be seen that the engagement of the extension 5with the end wall of the recess 6 will serve 'to arrange the shingles inthe row with their lower or exposed end edges in alignment; andfurthermore, since the extension 5 has a length that of the extensionat, the shingles will be spaced from each other a distance equal to thelength of the extension 4, as will be fully under stood from Figs. 2 and3. Accordingly, it will be seen that the extensions l and 5 and recess 6will serve as self spacing devices forthe' shingles. Those portions ofthe cuts C between the offsets E2, 3, are parallel to the remainingportion of the cut C; accordingly, when the shingles l are assembledside by side, as shown, they will be parallel to each other. "The lowerend wall 4c of the extension 4; serves as a guide to indicate to theworkman how much one row of shingles should overlap the next adjacentlower row to provide the proper or desired exposed surface in each Asshown in Fig. 3, the lower ends of the shingles in one row are alignedwith the end walls 4: of the shingles 1 of the next lower row so thatthe workman may leave the desired amount of exposed surface on thelatter row. It will thus be seen that the end walls serve to insureparallelism of the lower edges of the rows of shingles, and uniformityin the width of exposed surfaces in the rows, and that they also serveto co-operate with the interlocking or interengaging devices 5, 6, toprovice aligned relationship of all the shingles.

As shown in the drawings, the transverse cut D comprises a. plurality oftransverse sections, one for each shingle, connected by longitudinalsections, which serve to form the offsets 7) for the next adjacent setof shingles to be cut from the strip 1 As each transverse section of thecut D extends past the upper end. of the adjacent longitudinal cut C, itwill be seen that it serves to provide the upper end wall of theextension 5 on each shingle; further, since the lnngitudinal sections ofthe cut D are equal to the length of the offsets between the shingles ofa set, it will also be seen that each extension 5 is spaced from theupper end wall of the adjacent shingle a distance equal to the length ofthe offsets.

In 1 to 1 inclusive, the offsets 2, 3, are arranged at right angles tothe longitudinal sections of the cuts C. If desired, theoffsets forforming the extensions a, 5, and complementary recesses 6, 7, may beinclined relative to the longitudinal sections of the cut .1, as shownat 8 in Figs. 5 and 6.

To those skilled in the art of making articles of the classdescribech'many alterations in construction and widely differingembodiments and applications of my invention will sitiggest themselves,without departing from the spirit and scope thereof. My disclosures andthe description herein are purely illustrative and are not intended tobe in any sense limiting.

What I claim is:

1. A shingle having along one edge projections extending one beyond theother but of equal width longitudinally of the shingle and along itsopposite edge a recess complementary in shape and size to the shorterpro jection but in transverse alignment tosaid longer projection.

2. A shmgle hav1ng along its opposite edges sets of extensions of equalwidth but of different lengths and complementary recesses, said recessesbeing out of transverse alignment with said extensions, respectively, sothat when the shingle is correlated with another similarly formedshingleone of the extensions on one shingle will inter-engage a recesson the other shingle to align and space. them.

3. A shingle having along one side edge a pair of extensions ofdifferent lengths but of equal. width arranged. end to end, and

formed in its other side edge with recesses complementary to saidextensions but out of transverse alignment therewith, the uppermostextension being spaced from the up-- per end of the shingle a distanceequal to the width of each extension, whereby the extension of greaterlength will interengage 4. A shingle having along one side edge a pairof extensions of different lengths but of equal width arranged end toend, and

formed in its other side edge with recesses complementary to saidextensions but out oftransverse alignment therewith, the uppermostextension being spaced from the upper end of the shingle a distanceequal to thewidth of each extension, whereby the extension of greaterlength will interengage with the wall of a recess of another shingle tospace and align them, the lowermost extension serving as a guide inlaying the shingles of a superposed row of shingles.

In testimony whereof I affix my signature.
